In this paper, we study quasi post-critically finite degenerations for rational maps. We construct limits for such degenerations as geometrically finite rational maps on a finite tree of Riemann spheres. We prove the boundedness for such degenerations of hyperbolic rational maps with Sierpinski carpet Julia set and give criteria for the convergence for quasi-Blaschke products QBd, making progress towards the analogues of Thurston’s compactness theorem for acylindrical 3manifold and the double…

On geometrically finite degenerations I: boundaries of main hyperbolic components
In this paper, we develop a theory of quasi post-critically finite degenerations of Blaschke products. This gives us tools to study the boundaries of hyperbolic components of rational maps in higher…
On Deformation Space Analogies between Kleinian Reflection Groups and Antiholomorphic Rational Maps
In a previous paper [LLM20], we constructed an explicit dynamical correspondence between certain Kleinian reflection groups and certain anti-holomorphic rational maps on the Riemann sphere. In this…
Combination Theorems in Groups, Geometry and Dynamics
The aim of this article is to give a survey of combination theorems occurring in hyperbolic geometry, geometric group theory and complex dynamics, with a particular focus on Thurston’s contribution…
Polynomials with core entropy zero
TLDR
It is shown that a degree d post-critically finite polynomial f has core entropy zero if and only if f is in the degree d main molecule Md.

In this paper, we study hyperbolic rational maps with finitely connected Fatou sets. We construct models of post‐critically finite hyperbolic tree mapping schemes for such maps, generalizing…
Hyperbolic-parabolic deformations of rational maps
We develop a Thurston-like theory to characterize geometrically finite rational maps, and then apply it to study pinching and plumbing deformations of rational maps. We show that under certain…
Spinning deformations of rational maps
We analyze a real one-parameter family of quasiconformal deformations of a hyperbolic rational map known as spinning. We show that under fairly general hypotheses, the limit of spinning either exists…

Abstract We apply Thurston's equivalence theory between dynamical systems of post-critically finite branched coverings and rational maps, to try to construct, from a pair of polynomials, a rational…
Algorithmic aspects of branched coverings IV/V. Expanding maps
Thurston maps are branched self-coverings of the sphere whose critical points have finite forward orbits. We give combinatorial and algebraic characterizations of Thurston maps that are isotopic to…
Combining rational maps and controlling obstructions
We apply Thurston's characterization of postcritically finite rational maps as branched coverings of the sphere to give new classes of combination theorems for postcritically finite rational maps.…
Thurston’s pullback map on the augmented Teichmüller space and applications
Let f be a postcritically finite branched self-cover of a 2-dimensional topological sphere. Such a map induces an analytic self-map σf of a finite-dimensional Teichmüller space. We prove that this…
Global topology of hyperbolic components: Cantor circle case
We prove that in the moduli space Md of degree d⩾2 rational maps, any hyperbolic component in the disconnectedness locus and of Cantor circle type is a finite quotient of R4d−4−n×Tn , where n is…
Levy and Thurston obstructions of finite subdivision rules.
For a post-critically finite branched covering of the sphere that is a subdivision map of a finite subdivision rule, we define non-expanding spines which determine the existence of a Levy cycle in a…
